The Recent Flagged box shows you the list of recently disclosed, or flagged, short positions in your current group. The list shows you which company is shorted and who the position holder is, as well as the change, and the current position in percent of outstanding shares.
This list is only relevant for companies which are listed in the European Union. European Financial regulators have to publicise short positions over 0.5% of the outstanding share in a company, including the name of the position taker.
You can filter the list by typing in the text boxes and change the sorting by clicking on any column header.
